Abstract

Aims: To evaluate the effect of different nutrient management practices on growth, yield and yield attributes of wheat. Study Design: Randomized Block Design (RBD). Place and Duration of Study: The experiment was conducted during Rabi season 2016-17 at Instructional Farm of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar, Kumarganj, Ayodhya (U.P.) Methodology: The experiment consisting of 10 treatments, T1 Control (N-0,P-60,K-40Kg ha-1); T2 (Azotobacter); T3 (60 kg Nitrogen ha-1); T4 (40 kg Nitrogen ha-1 + Azotobacter); T5 (80 kg Nitrogen ha-1); T6 (60 kg Nitrogen + Azotobacter ); T7 (100 kg Nitrogen ha-1); T8 (80 kg Nitrogen ha-1 + Azotobacter); T9 (120 kg Nitrogen ha-1); T10 (100 kg Nitrogen ha-1+ Azotobacter) were laid down in triplicate plots in Randomized block design (RBD).Wheat variety PBW-343 was taken as test crop. Results: The results revealed that the application of chemical fertilizers @ 100 kg Nitrogen ha-1+ Azotobacter (T10) recorded the highest growth attributes viz. Plant height, dry matter accumulations, and yield attributes viz. number of grains per spike, weight of spike, test weight, grain yield, straw yield and harvest index.
